WP 34S solve an integral

Code:

...
RDP 05    // round to e.g. 5 decimal places
x≠0?      // if result does not round to zero
x<> L     // recall the original unrounded value
RTN

This way the solver always gets the exact function result, and only values below the (here) 5–digit threshold are rounded to zero so that the solver quits.

Thanks Dieter!

If I understand correctly, the x≠0? and x<> L steps ensure that the latest exact (versus rounded) SLV guess is passed back to the SLV routine?
